Operators

operator HBITMAP

Returns the Windows handle attached to the CImage object.

The constructor.

Operations

AlphaBlend	Displays bitmaps that have transparent or semitransparent pixels.
Attach	Attaches an HBITMAP to a CImage object. Can be used with either non-DIB section bitmaps or DIB section bitmaps.
BitBlt	Copies a bitmap from the source device context to this current device context.
Create	Creates a DIB section bitmap and attaches it to the previously constructed CImage object.
CreateEx	Creates a DIB section bitmap (with additional parameters) and attaches it to the previously constructed CImage object.
Destroy	Detaches the bitmap from the CImage object and destroys the bitmap.
Detach	Detaches the bitmap from a CImage object.
Draw	Copies a bitmap from a source rectangle into a destination rectangle. Draw stretches or compresses the bitmap to fit the dimensions of the destination rectangle, if necessary, and handles alpha blending and transparent colors.
GetBits	Retrieves a pointer to the actual pixel values of the bitmap.
GetBPP	Retrieves the bits per pixel.
GetColorTable	Retrieves red, green, blue (RGB) color values from a range of entries in the color table.
GetDC	Retrieves the device context into which the current bitmap is selected.
GetExporterFilterString	Finds the available image formats and their descriptions.
GetImporterFilterString	Finds the available image formats and their descriptions.
GetHeight	Retrieves the height of the current image in pixels.
GetMaxColorTableEntries	Retrieves the maximum number of entries in the color table.
